Much warmer temperatures in most of the area today as winds shifted to the south, highs were in the 70s to lower 80s with much cooler temps closer to Lake Superior (mid 40s to mid 50s) due to an easterly breeze. There was a cold front extending from northern Minnesota to western Minnesota with some rain occurring near that front today in western-northwest parts of the state.
Cold front moves through the Northland tonight through Saturday morning — Mostly cloudy skies with occasional rain showers as that front moves through. Not everyone will get rain, unfortunately, but some locations should be able to squeeze out up to a quarter inch or so of rain.
